09CuPCrNi-B weathering steel has long way to go to achieve better performance

The company specializes in the research and development, production and sales of 09CuPCrNi-B weathering steel seamless pipes, longitudinally welded pipes, large-diameter welded pipes, API 5L welded pipes, spiral welded pipes, and large-diameter thick-walled straight seam steel pipes. The company has 09CuPCrNi-B weathering steel five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,09CuPCrNi-B weathering steel rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.

EN10028-2 P235GH steel plate is a non-alloy quality steel with high temperature performance, executive standard: EN10028-2. Steel number: 1.0345. 09CuPCrNi-B weathering steel, P235GH pressure vessel steel has good plasticity, toughness, cold bending performance and welding performance. The P235GH presure vessel plate and sheets size, shape and allowable deviation of the steel plate should meet the requirements of EN10028-1 2007 + A1: 2009.

The main metal material 09CuPCrNi-B weathering steel used to make the boiler is steel. The main boiler body is composed of the parts which bear static load under normal temperature and the parts which bear high pressure and high temperature. The former part can be made of general structural steel, while the latter part must be made of steel with special properties, i.e. boiler steel. Boiler steel is required to have good high temperature resistance, stable structure, machining performance, etc. properties.

If the chromium content in 09CuPCrNi-B weathering steel alloy steel reaches about 12%, dense chromium oxides will be formed on the surface of the steel, which will greatly improve the corrosion resistance of steel in oxidizing media. Chromium, aluminum, silicon and other elements can improve the oxidation resistance of steel and the corrosion resistance of high-temperature gas, but excessive aluminum and silicon will deteriorate the thermoplasticity of steel.
